I understand it. There are those outside the film community who wouldn't be able to see his work if he only posted it here. Perhaps that's what he meant with his reply. Giving anyone the initial benefit of the doubt seems reasonable enough!
I do think, though, that he should be springing for a membership. We all get so much from this forum, that the price is far less than the value we get in return! Just the time put into keeping this place for us is worth far more than the cost, and deserves something.
I hope I'm not being out of line.
